JavaFX Links of October 2026

Oct 30, 2026 · 8 min read

Here are the JavaFX LinksOfTheMonth of October 2026. You can find the weekly lists on jfx-central.com. Did we miss anything? Is there anything you want to have included in one of the next overviews? Let us know via links@jfx-central.com.

Core

Applications

  • Max Xiong shared a new screenshot of DataCollie, his ongoing #BuildInPublic project, noting that “PostgreSQL’s privilege management is much more complex than MySQL’s. Still, I’m making a little progress every day.”
  • Mike built Klunk, a JavaFX log viewer for making large logs easier to navigate and search. It merges logs from files, databases, Kubernetes pods, SFTP and HTTP into one color-coded stream, with SQL-like filtering, bookmarks, real-time tailing and SQLite-backed handling of millions of rows. Free to use, with bundled runtime for Windows, Linux and (untested) macOS.
  • Following up on last week’s internal JavaFX tool for automated test recording of temporary power equipment, @afparks shared two new videos. The latest shows the new users and roles pages, with a permissions table that has sticky headers staying in place while scrolling, and an overlapping scroll bar that floats over the rows instead of taking up space on the right.
  • Frank Delporte released MelodyMatrix 2.0.0 with a new Learn section with lesson cards tracking level, duration and progress, a Fly-Over view showing the sheet music in 3D with notes highlighted during playback, and a Convert feature that turns mp3, wav and other audio files into MIDI locally.
  • AsharPeshimam published a Java PDF app on the Microsoft Store, shared the story on r/JavaFX, and asks for feedback.
  • Klunk, a JavaFX log viewing application was shared on r/JavaFX by XenFive. “It’s currently beta, but I use it daily without issues and figured others might find it useful too. Happy to hear feedback, bug reports, or feature ideas.”
  • Max Xiong is preparing to launch DataCollie, his database client built with JavaFX, after a long #BuildInPublic journey: “Doing some final prep before launching DataCollie. So many edge cases to handle!”

Games

Components, Libraries, Tools

  • Frank Delporte released version 1.2.6 of Lottie4J, the library to parse, generate & play Lottie animations natively in JavaFX. “It’s a minor update which reduces the logging when animations are started and stopped. Thanks to David Gerber for the merge request.” All info on the Lottie4J website.
  • Frank Delporte announced a new version of Lottie4J, the Java and JavaFX library to render Lottie animations. “Release 1.2.7 doesn’t bring new features, but focuses fully on performance. Improvements: image assets are decoded once, and optimized track mattes.” Read more on this blog post.
  • Mohd Dilshad Khan shared a tip on switching themes while a Java app is running, without a restart or losing state. In JavaFX it comes down to replacing the stylesheet on the scene with scene.getStylesheets().setAll(...), so themes live in CSS files a designer can tweak. For Swing, FlatLaf offers the same with FlatDarkLaf.setup() and FlatLaf.updateUI(). You can find his project on GitHub.
  • Frank Delporte announced version 0.0.4 and 0.0.5 of Sheetmusic4J, the library to parse and render sheet music natively in Java/JavaFX. These releases include new Node-based and 3D fly-over views, and add support for the LilyPond format: “load such a file and render it natively in JavaFX, without running LilyPond.” It also brings engraving improvements like better tuplet placement and octave clef support. A video with a demo of the new views is available on YouTube.
  • Frank Delporte released Sheetmusic4J 0.0.5 with LilyPond import/export: Adds LilyPond (.ly) import/export through the unified ScoreFile facade via a parser/interpreter/assembler pipeline, plus engraving improvements such as better tuplet placement and octave clef support — building on the earlier 0.0.4 release, which added the clickable/draggable NodeSheetView and 3D FlyOverSheetView.
  • Libán Bande González announced Vitra, a modern UI library for JavaFX with Gantt, Kanban, calendar, charts, Fluent-inspired materials, glass surfaces and custom windows. All controls support CSS and runtime theme switching, and there are no external dependencies. More info is on the website.

Podcasts, Videos, Books

  • Josh Long features Andres Almiray in a Spring Office Hours podcast episode. A wide-ranging, high-energy conversation about the future of desktop Java, the pain of Electron, the elegance of JavaFX, and JReleaser — the tool that helps Java projects publish releases, package native installers, generate distribution bundles, compute signatures and checksums, and automate releases across GitHub, GitLab, Maven Central, and more.
  • Libán Bande González announced his book “Skinning JavaFX Applications”, “a practical, code-first book built from years of shipping real desktop business applications,” focused on the Control-Skin architecture for building custom controls and skins. It covers custom window chrome, runtime theme switching, modern design materials like Mica and Acrylic from Fluent Design, and micro-interactions, arguing that “CSS is not enough” to make JavaFX apps look like modern Microsoft or JetBrains interfaces. More info on the book’s website.
  • Adam Bien talks with guest Ingo Kegel on airhacks.fm #419: “Agents Have No Runtime Insight”: Discusses giving AI coding agents JVM runtime insight through a JProfiler MCP server, including how an agent loop was used to double jclasslib’s performance by outperforming ASM’s bytecode parser, alongside memory-profiling fundamentals like dominator trees. They also touch on a possible Swing and JavaFX revival, because both ship with Java and LLMs know them well.

Tutorials

  • Sombriks wrote The state of java desktop, comparing Swing, JavaFX, SWT, and TamboUI through a small todo app example, noting jpackage has made distributing Java desktop apps practical, and describing JavaFX as “the really modern one” with native property bindings, cleaner event handling, and CSS-styled scene graph, best suited “for really big projects”.
  • Libán Bande González wrote “Building a JavaFX Code Editor Control”, showing how to build a code editor with the Control/Skin architecture: virtualized line numbers, regex-based syntax highlighting, bracket matching, multi-cursor editing, undo/redo, and autocomplete. The code and gutter are two synchronized ListViews so line numbers stay fixed during horizontal scrolling. The full implementation is part of his book “Skinning JavaFX Applications”.
  • sosuisen published “JavaFX Getting Started with VS Code” on his renewed personal website. The article was originally written for JFX Central and was rewritten for Japanese readers and his students. The page has a toggle between Japanese and English. Announcement on Bluesky.
